UCC27223 is a high-speed synchronous buck driver for today’s high-efficiency, lower-output voltage designs. Using Predictive Gate Drive® (PGD) control technology, these drivers reduce diode conduction and reverse recovery losses in the synchronous rectifier MOSFET(s). The UCC27223 includes an enable pin that controls the operation of both outputs. A logic latch is also included to keep both outputs low until the first PWM input pulse comes in. The RDS(on) of the SR pull-down sourcing device is also minimized for higher frequency operations. This closed loop feedback loop also improves driver stability and efficiency.
